DNV GL © Monday, February 25, 2019
Need for long term policy – Phased development offshore wind in Netherlands
Short Term (to
2023)
Three phase (parallel) development:
➢ North Sea Wind Power Hub ➢ Far-reaching international
cooperation necessary
Medium Term (to
2030)
Long Term (to
2050)
➢ Currently under development (near shore)
➢ Use full potential near shore locations ➢ Prepare for large scale and international
cooperation

How to deal with further increase of offshore wind – grid optimization
32
The development and integration in the electricity system of large scale offshore wind energy requires knowledge, experience
and high investments in the onshore grids
DNV GL © Monday, February 25, 2019
Research and innovation needs – DNV GL participates in Europe’s PROMOTioN project with over 30 partners
▪ PROMOTioN Progress on meshed offshore transmission networks – European research will prepare next
generation technologies on HVDC addressing following challenges:
35
=~
– Offshore requires cables & platforms
– Long cables require HVDC
– HVDC requires converters
– HVDC network requires HVDC control & protection
system
– HVDC protection system requires HVDC switchgear
/ circuit breakers
– Transnational network
o Regulatory differences
o Business models
o Governance
o Financing
DNV GL © Monday, February 25, 2019
Summary
▪ Stress in offshore supply chains
▪ Grid extensions onshore - optimization
▪ Research and innovation needs like PROMOTioN
▪ Risk mitigation and reduction
– Power system studies
– Technology qualification, 3rd party review, and verification
– Certification, e.g. DNVGL-SE-0190 Certification of wind power plants
▪ Establish good long-term planning processes, especially for energy scenarios and grid
infrastructure to ensure that energy transition becomes a success
– Stable environment for investors, operators, all stakeholders
